Changes
Initial Release
â Updated all output switching frequency references to fsw1 from 200 kHz to 192 kHz.
â Updated all output switching frequency references to fsw2 from 80 kHz to 76 kHz.
â Updated front page title, features, and common applications.
â Updated front page block diagram.
â Updated Section 3. Typical Connection Diagrams to show 10 ïF and 0.1 ïF power-supply decoupling
capacitors.
â Reorganized location of individual specifications in electrical characteristics tables based on measured
device performance in different operational modes (âElectrical Characteristics - All Operational Modesâ
on page 9, âElectrical Characteristics - SD Modeâ on page 10, âElectrical Characteristics - FSD Modeâ
on page 11, âElectrical Characteristics - HD Modeâ on page 12, and âElectrical Characteristics - FHD
Modeâ on page 13).
â The following specification changes have been made in âElectrical Characteristics - SD Modeâ on
page 10, âElectrical Characteristics - FSD Modeâ on page 11, âElectrical Characteristics - HD Modeâ on
page 12, and âElectrical Characteristics - FHD Modeâ on page 13:
â Added âCommon-Mode Rejection Ratioâ test conditions (Vripple = 1 VPP and fripple = 217 Hz)
â Updated âSignal to Noise Ratioâ to be specified as A-Weighted
â Updated âIdle Channel Noiseâ to be specified as both A-Weighted & Unweighted
â Updated âIdle Current Drawâ to be specified with no load at 3 voltages (5.0 V, 4.2 V, and 3.7 V)
â Changed âMax Input Before Clipping specification to âInput Voltage @ 1 % THD+Nâ
â Updated specification typical values for 1% Output Power, 10% Output Power, THD+N @ 1 W, SNR
A-Weighted, Idle Channel Noise A-Weighted, Idle Channel Noise (unweighted), Frequency
Response, Output Switching Frequency, Input Impedance, and Input Voltage @ 1% THD+N
â Updated âOperating Efficiencyâ to be specified with 8 ï + 33 ïH and 4 ï + 33 ïH in âElectrical
Characteristics - All Operational Modesâ on page 9.
â Modified âPower-Up Timeâ specification into âStart-Up Timeâ and âZero Crossing Power-Upâ and added
a cross-reference in âPower-Up & Power-Down Characteristicsâ on page 14.
â Moved power-up and power-down timing specifications from âElectrical Characteristics - All Operational
Modesâ on page 9 to their own specification table, âPower-Up & Power-Down Characteristicsâ on
page 14.
â Renamed âThermal Error Wait Time (WTE)â to âThermal Error Retry Time (RTE)â in âElectrical
Characteristics - All Operational Modesâ on page 9 and in Section 5.5 Over Temperature Protection and
added (Note 10) Thermal Error cross reference from spec table to description section.
â Updated âOperating Efficiencyâ specification (ï¨) in âElectrical Characteristics - All Operational Modesâ
on page 9.
â Updated âMOSFET On Resistanceâ specification (RDS(ON)) in âElectrical Characteristics - All
Operational Modesâ on page 9.
